Oh, it works!  Thanks.  So, Emacs links some essential one only
when --with-w32, doesn't it?  I don't know what it is, but I hope
Cygwin Emacs uses it no matter what GUI is chosen.  My configure
options are:

--verbose --with-x-toolkit=lucid --without-imagemagick --without-dbus
--without-gconf --without-gsettings'
